Bindusara Maurya (r. c. 320–272 BCE) was emperor of the Maurya Empire. During his reign, the empire expanded southwards. He had two well-known sons, Susima and Ashoka, who were the viceroys of Taxila and Ujjain. The Greeks called him Amitrochates or Allitrochades – the Greek transliteration for the Sanskrit word Amitraghata "Slayer of enemies".
